So I use to play dayz singleplayer so much I loved it.. and i stopped for a while but then I wanted to pla it again so I got dayz commander back and tried to install dayz 188.8.131.52 because I wanted to play namalsk release and it came up with a red triangle I did alot of researching about it but i couldent find anything please help!
I just had the exact same problem, it turns out some of the CDN servers for DayzCommander are either down or have basically crashed.
What you need to do is have DayZCommander open and flush the DNS on your machine.
To do that, goto the Start Menu and type Command Prompt. Run it as an Administrator
Open DayZ Commander
In the Command prompt, type ipconfig /flushdns
Now attempt to download or update one of the DayZ Mods. Every time you get the error, once again do the command. Each time you will see it will refuse from a different IP Address. keep flushing your DNS until it works, and voila! You'll be downloading DayZ
